Requirement

Auto-redirect must not be used.

Error

Auto-redirect used.

Short Description

meta elements that contain a http-equiv attribute with a value of "refresh" cannot contain a content attribute with a value of (start, case insensitive) "http://".

Rationale

Developers cannot predict how much time a user will require to read a page; premature refresh can disorient users. Content developers should avoid periodic refresh and allow users to choose when they want the latest information.

How To Repair

Use a server-side redirect or place a link on the page that allows users to go to the new page.

Steps To Check

Procedure

1. Check each meta element for an http-equiv attribute value of "refresh" and a content attribute value that starts with "http://".

Expected Result

1. The content is expected to contain no meta elements that have an http-equiv attribute value of "refresh" and a content attribute value that starts with "http://".

Failed Result

1. Use a server-side redirect or place a link on the page that allows users to go to the new page.
